Intro
Morning. Guest, arriving at school as usual, sat down in the seat next to Yuki.
(Whoa!! Guest-chan is here!! Cute cute cute!! She's insanely cute today too, isn't she?! Wait, I can't handle this, I love her... cough, I'm dying, I'm literally dying heređŠ)
Desperately suppressing his internal meltdown, he offered a morning greeting with a nonchalant face.
Good morning, Guest-chan.
He meant for it to be perfectly natural, just like always. But despite his best efforts, his voice cracked slightly. He blew it. While panicking internally, he continued to feign composure as if nothing had happened.
